%Inconsistent address and mask

[WanderingSailor]

I have the following entries in my config file:

205.10.85.0 255.255.255.240 tunnel0
205.10.85.32 255.255.255.240 tunnel1
205.10.85.48 255.255.255.240 tunnel2
205.10.85.64 255.255.255.240 tunnel3
205.10.85.90 255.255.255.240 tunnel4
205.10.85.96 255.255.255.240 tunnel5
205.10.85.112 255.255.255.240 tunnel6
205.10.85.128 255.255.255.240 tunnel7

Another network person requested that the address for tunnel7 be changed to:

205.14.81.114 225.255.255.240 tunnel7

And when I type this in, I get the error,
'%inconsistent address and mask'

I have attempted to explain to him that I cannot use this address as it falls in the range of allowable hosts for the 205.14.81.112 subnet, but he says it can be done. Without changing any other subnets/masks, anyone know how?

Thanks!

I agree that the address falls into the 205.14.81.112 subnet. Your valid hosts should be .113 - .126

Can you post your config?

Did you remove the config line:

"205.10.85.128 255.255.255.240 tunnel7"

before adding the new line in?
That could cause the problem.

This is basic subnetting. So few people know it.

I woild make him prove it to you in binary that it will work. Then make him do it on the router. I bet he will not. If he does you will learn something new. He is breaking a basic rule of IP networking. You can always play dumb and make them prove it.

205.14.81.144/28 is a host address. .112 is the network, and .127 is the broadcast for that subnet. Those are the facts.

Is this supposed to be 205.10.85.x or 205.14.81.x ?

205.14.81.114 /28 does not fall within the above specified 205.10.85.112 /28 subnet.

Although, as stated correctly above, it is a host address and not a network address; so it is still an invalid entry.

Just trying to figure things out.

Despite the typos , I agree that everyone's correct.

.114 is a host address, you must use the network address of .112 on a /28 bit mask.

Your other network person is wrong.

Thanks everyone, for your input...It was a typo on my part, it could have ben either way, but the third octet was supposed to be the same...

Anyhow, he was wrong and I (and you) were correct...He realized it after coming to my workspace and seeing it for himself...

Thanks for the feedback...
